2. Just consider each locus seperately, the first one requires you to shade inside the circle, the second inequality requires the angle from z=-6 to be greater than arctan(1/2), so the region above this is shaded.

What's confusing me really is the inequality in |z-6+3i| > 3|z+2-i|. What does this mean? Why isn't it an equals sign instead?

The inequality just means that there's an area to shade rather than a line/circle to draw.
